Finn and Jake sat in the waiting room of the candy kingdom's hospital. Jake was moving around in his chair obviously uncomfortable and bored. Jake looked at Finn. Finn looked quite upset and was tapping his foot repeatedly. Jake out of boredom, shape-shifted into Finn and smiled at him. Finn however, wasn't paying attention. Jake frowned and groaned. He took Finn's hat off his head and put it on his own. Jake thought that if he did that he would of got Finn's attention. Jake sighed deeply. Finn sat there still until a sting of blonde hair fell in his face. He tried to move it back inside his hair, but he felt bare hair. He ran his hand in his hair again then looked at Jake. "Jake, give me my hat back!" He shouted. A smile grew on Jake's face and he shook his head. Finn reached for his hat, but Jake stretched his neck out of Finn's reach. Finn climbed over Jake's body and Jake tried to push him away. Nurse Ice cream came from a door and spoke. "Finn and Jake, you can come in now." She said and walked down the hall leaving the door she exited open. Finn and Jake got up and Finn snatched his hat off Jake's head and put it on. They both walking into the room. "Are you ok?" Finn said to her quickly running over. "Yea, I'm fine. She told me the fluid inside that thing was poisonous to animals." She said and stood up off of the metal bed. "Did she say you could leave yet?" Finn asked. "No, but whose gonna stop me?" Finn opened his mouth to say something, but didn't. She grinned and opened a window. "Do you ever use a door?" Jake asked crossing his arms and frowning. "Nope, doors are for losers." She said and jumped out the window. Finn and Jake looked at each other and shrugged. They followed her out.

"Now where are we heading?" Mercury asked. She watched as the grass turned to ash as she walked. "To see Marceline. I want you to meet her." Finn said. "Um Finn, that would be a bad idea. She and Marceline are-" Jake didn't finish. Both Marceline and Mercury scares him, but together? This can't be good. "We're here!" Finn shouted smiling. Mercury stopped in her tracks. Her nose started twitching and she started to growl. "What's wrong?" Finn asked stopping as well. "I don't like it here... Something is wrong." Mercury growled again glowing inside the cave. "Its ok, I'll bring Marcy to you instead." Finn ran to the house's door. "M-Mercury we should leave." Jake knew that this idea Finn had wouldn't be good. The aroma Mercury was smelling grew louder and the louder it got louder she growled. The door finally opened and a vampire holding her noise in pure disgust appeared. "Hey, Finn. Geez! Is that you who smells terrible?" She sniffed him. "Yep, who threw you into a sewer. The smell isn't that strong on you. What is it coming from?!" She said. Finn shrugged. "I smell nothing, but I have someone I want you to meet! Come on!" Finn shouted and Marceline followed.

Mercury and Marceline looked at each other. "Your the one who smells terrible!" They exclaimed at the same time. "Blood sucking Demon." Mercury glared. "Such a aggressive cut-throat Beast." Marceline frowned. "I'm leaving, it stinks too bad in here." Mercury said simply and ran out the cave. "Great! The air in here was being polluted!" She shouted and stomped into her house. Finn stood shocked. "You Finn... messed up." Jake patted his back.

They followed black foot prints that were in the grass to a field. "Where are you going?" Finn asked running up to her. "Home. I should not stay here." She turned to face him. "Yes you should! You killed a monster remember." She shrugged. "Yes! I killed! Not for good! I killed because I wanted to! If I was not suppose to do it, I would of anyway! Its a instinct! I'M A KILLER! ACCEPT IT!" She shouted out loud. Finn didn't believe it. He grabbed her hand no matter how much it hurt. This surprised her. "NO!" He squeezed her hand. "I know there is good in you! You need to accept that. Your still part human, don't forget what and who you are." His hand felt numb. Mercury tugged her hand, but Finn had a firm grip on it. She sighed and looked away from him. "I'll leave you guys alone.." Jake ran home. They both didn't noticed Jake at all. "Look.." Finn grabbed her chin and turned her head to face his face. Pain shot threw his hand but he ignored it. "I know you think you have no chance fitting into this world, but you really do. PB, FP, Marcy don't know what they are talking about. You can be a pain, but you still mean well actually more than well. You need to stop think about the negative things and look at the positive. Not everyone is gonna think your bad. I know your not a bad person, but a nice and beautiful one. Inside and out." Finn smiled at her. He blushed when he thought back on the last two sentences he said. She looked at Finn speechless. Their faces were inches apart. "Finn... You really think so..." She looked down grinning shyly for a second. "I know so." He whispered. Without thinking, Finn kissed her. Mercury was shocked for a moment, but ended up kissing him back. They started kissing gently then they started getting wild with it. Mercury saw red spots on his arms and hands, so in the middle of the kiss she whispered a chant. Suddenly, Finn's body was covered in blue and he didn't feel any pain. Finn deepened the kiss. "Finn..." She moaned. Finn had her against a tree. She took off his hat and ran he hands threw his blonde hair. Finn has never felt this way before. He didn't know how far he could go before they decided to stop. He started to kiss her neck all over. "Oh glob Finn... we need... to stop.." She growled low in her throat. Finn pressed up against her and rubbed his hands up and down her body. When he touch her thigh, so moaned loudly and pushed him off her, but not hard enough for him to fall down. They both were panting heavily and blushing. "We...should go now.." Mercury said grinning a little. Finn nodded while smiling.

At the tree house, everyone had on their pajamas and were getting in bed. "Wait, whats on your neck?" Jake asked Mercury. She touched it and her face was a little red. "Injury." She said a little too quickly. Jake didn't believe her, but didn't say anything and crawled into bed and quickly fell asleep. "Um, Mercury..." Finn scratched his head and sat on the bed. "Yes?" She answered at turned to face him. "You... Uhhh...did you.. enjoy it.." He asked shyly. "I...yea" She said and turned back around. He nodded and got in the bed and Mercury did the same. "Would we do it again?" Finn whispered so no one would hear.
